FoxPro System Information Function

• Microsoft Visual FoxPro for Windows, version 3.0
• Microsoft FoxPro for MS-DOS, versions 2.0, 2.5 and 2.5a
• Microsoft FoxPro for Windows, versions 2.5 and 2.5a

SUMMARY

The SYS functions provide system information about a Microsoft FoxPro installation. The values SYS(2011) through SYS(2021) are new to FoxPro version 2.0.

To query system information interactively, enter

   ? SYS(#)

Another method of checking system information is to use the following:

   WAIT WINDOW SYS(#)

These alternative methods offer at least one advantage over the ? SYS(#) method since the ? SYS(#) method writes to the last cursor position for the active window, and it is possible to have other objects obscure the output of the ? SYS(#) command so that you can't see where the returned value is being displayed.

The output from the WAIT WINDOW SYS(#) method is displayed at a predictable location in a predictable fashion. If the Debug window method is used, the output is displayed in the Debug window.

For more information, see pages 3-874 through 3-891 of the "Microsoft FoxPro Commands & Functions" manual for version 2.0, or see pages L3-1065 through L3-1083 of the "Microsoft FoxPro Language Reference" manual for version 2.5.
